CAR-COUPLING.

SPEGIFIGATIONforming part of Letters Patent No. 286,622, dated October16, 1883.

Application filed September '2, 1883. (No model.)

To all whom it may concern:

Be it kn own that L-hIIOHAEL E. MCDONALD, a citizen of the UnitedStates, and a resident of Scranton, in the county of Lackawanna andState of Pennsylvania, have invented certain new and useful Improvementsin Gar-Couplings; and I do hereby declare that the following is a clear,full, and eXact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective View of myin1- proved car coupling, showing the link inserted. Fig. 2 is avertical longitudinal section with the link removed prior to coupling.Fig. 3 is a similar view-, showing the link inserted; and Fig. at is aperspective front view of the draw-head.

Similar letters of reference indicate corre sponding parts in all thefigures.

My invention has relation to socalled automatic or self-actingcar-couplings; and it consists in the improved construction andcombination of parts of the same, which will be hereinafter more fullydescribed and claimed. a

In the accompanying drawings, A denotes the draw-head of my improvedcar-coupling, and Bthe mouth of the same, which is narrowed graduallytoward its rear part,.O. In the front part of the mouth or opening B isa transverse recess, D, in which is pivoted a plate, E, operated by ahandle, F, for adjusting the elevation of the link G when this isinserted into/the draw-head. The back part of the draw-head has avertical slot, H, which opens into the mouth B C at I, and into thisslot is pivoted the hook-shaped latchor stop J the weighted lower end ofwhich is hung upon the bolt K, inserted transversely through the rearend of the draw-head. The free end of the latch J will by the gravity ofthe latch be caused to project through the slot or opening L in abearing, M, on top of the drawhead, so as to be in a line with theaperture N in which the coupling pin or bolt 0 works. In Fig. 2 of thedrawings I have shown the hook-shaped latch in this position, closingthe aperture N at its lower end and supporting the coupling-bolt O, andwhen the latch is'in this position it will be seen that it projectsthrough the slot or opening I in the back of the link-chamber B C. Itfollows that when the link is inserted it will strike against thisprojecting part, (indicated by the letter J,) an d thus tilt the latchback in its slot or recess H, which releases the coupling pin or boltand allows it to drop down through the link, andthus effect thecoupling. The free end of the link is adjusted at its proper elevationto engage the opposite draw-head by means of the adjusting-plate E.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States The combination, in a car-coupling,of the draw-head A, having link-chainber B C, vertical recess H,transverse recess D, and the slots or openings I and L, hinged plate E,having lever F, and hook-shaped gravity-latch J J, adapted to projectwith its free end through the slot L into the bolt-bearing M, the wholeconstructed and combined substantially as and for the purpose shown andset forth.

In testimony that I claim the foregoing as my own I have hereuntoailixed my signature in presence of two witnesses.
